To all whom may concern if Be it. known that we, EMILE ALFRED zens of the Republic of France, and residents of 95 Rue Pronnet, Neuilly, Seine, France. have-invented a Dish-Cleaner, of which the following is a specification.

This invention relates to improvements in dish washing machines and consists in devices for carrying the dishes abreast of a plurality of sets of nozzles which are directed toward the moving dishes and arranged in a manner to successively wash, cleanse, rinse and dry the same.

The invention is designed to utilize liquids of different character in connection with the different sets of nozzles and devices are provided for initiating a How of the several kinds of liquid from receptacles containing the same to and through said nozzles.

The invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed ont and ascertained 'in and by the appended claim. l

In the drawings-: Figure 1 is a vertical cross-sectional view ofa device embodying the main features of our invention, and taken approximately .on the line 1.1 of Fig. 2. Fig. 2 is a plan view of the carrier mechanism for the dishes with the tanks omitted and illustrating the-arrangementof the nozzles with respect to the carrier. F 1g.

3 is a view in side-elevation of the parts shown in Fig.2. -Fig. 4 is a longitudinal sectional view on line 4-4 of Fig. 1.

Referring specifically to Figs. 1 and 2, Z designates a casing which isdivided by pertitions n and m into a .central heating and pump chamber" Z, carrier chamber 1 and container. chamber 1 At'oposit-eends of the carrier chamber. Z vertical shafts a are provided andv said shafts carry double sheaves a about which are trained carrier chains a a. Said chains 11 a are provided with upper and lower dish holder supports 5 and b which are secured to dish holders 6 in a manner to support the same. Said dish holders 6 consist of curved strips of metal bent to conform to and receive plates 0 and said plates are held in place by retainers in the form of fingers b secured to Specification of I ietters Patent.

Mot ve power may be applied to operate the carrier chains in any desired manner.

It will be seen by reference to Fig. 2, that when the carrier chains are in motion the plates 0 will travel in parallel relation with each other at suitable distances apart and in vertical positions throughout their path of movement. Durin the travel of said plates the same are su jected throughout a period of their movement to a washing action of hot water which is preferably laden with a substance adapted to facilitate'the washing action but which substance need not necessarily be a washing compound. I prefer to employ saw-dust in this connection. Immediately after the washing action the plates are subjected to a cleansing treatment and for this purpose I desirably employ a suitable .carbonated water. ,Subsequently the plates are subjected to a drying treatment of hot air of the plates saw-dust or other particles that may have adhered thereto whereupon the to remove from the surfaces dishes will be in condition to be placed upon a shelf orother repository for the dishes.

The plates erably at is discharged for lnserting and. withdrawing the plates may not constitute a feature of the invention such means are not hereinspecifically shown and described. First referring to the wash- ,ing treatment, thereis provided a plurality of nozzles cl disposed in a manner to direct the washing fluid on both surfaces of each plate. As shown said nozzles d are inclined opposing angles, two of said nozzles directing the'washing fluid in a direction reverse to the travel of the. plates and two of said nozzles. directing the washing fluid substantially in the direction of the travel of the plates. i

It will-be seen by reference to Fig.- 3, that as thei plates move abreast of the nozzles their vertical faces will present or occupy a continuously. changing position with respect to axes of the nozzles thereby insuring contact of the streams issuing from said nozzles throughout the entire areas of both sides of each plate. Referring to Fig. 3, it will be seen that the first plate advancing toward the first rearwardly directed nozzle will receive the stream issuing therefrom adjacent its lower portion and as such plate advances to a position adjacent said nozzle the stream issuing therefrom will have gradually passed across the surface of and will be directed toward upper portions of the plates. It will also be seen that as the plate recedes from the first forwardly directed nozzle the stream will engage the upper portion thereof and as the plate further recedes the stream will pass across the surface of each. plate-and will engage lower portions thereof thereby affording a most eflicient and effective cleaning action. The nozzles 01 are connected with a pipe 9 which is fed bya pipe 9' froma pump h. Said pum h is connected with a tank a. at 7'. It wi 1 be seen by reference to Fig. 1 that the washing fluid issuing from the nozzles d will descend into the tank a. as indicated by the arrow and will be continuously re-used'. A plurality of nozzles e are disposed in advance of the nozzles a in such a manner as to act upon the plates after the same have been washed. Said nozzles e are connected with a pipe g" which is fed through a pipe the plates are cleansed and the nozzles e are disposed in a manner to carry out the cleansing operation similarly to the washin operation.

it will be noted by reference to Fig. 2, that the pipe g is located adjacent the sheave a and I desirably utilize the time required for the plates to pass around the sheave a to permitthe dishes or plates to drain. After the plates have passed the sheave a as indicated by the arrow they will be subjected to a drying treatment by the nozzles of the pipe g which are preterably similar to the nozzles e and d. The pipe may be provided as shown in Fig. l with a plurality of nozzles 12, the hot air being supplied throu h a pipe 72 communieating w1th any suita le source of supply.

Referring to Fig. 4, the tanks 0', b and a are fed from a supply tank 7. Said tank f is provided with a discharge or delivery pipe f which as shown terminates in a rose F. A valve and float arrangement f and f serve to maintain the water in the tank 0' at a predetermined level. A suitable heating device or furnace o is provided for keeping the water in the tank 0 at tanks 0' and b and a so constitutes'a feed pipe for the tank I)". Such impurities as may be floating on the surface of the tank 0" will not be taken up by the pum owingto the low position of the inta e j. The same is true with respect to the tank a? which also has a low outlet j for the pump it.

An overflow pipe comiects tank 6* with tan-k a -"and carries off the floating impuri ties. The-water in the tank a is provided with a suitable quantity of washing material such as saw-dust. A refuse tank d is provided adjacent the washing tank a and is connected therewith by an overflow pipe (Z A siphon discharge (1* may be provided for the tank 03 and also a valve outlet d, the latter being adapted for use when the tank is to be cleaned. It will be seen that the water in all of the tanks will be heated by the furnace u and will be fed from the tan 7' and that the lioating impurities of tanks 0 and a will be taken off from the surface of the water contained therein and delivered to the refuse tank.

We claim:

In a dish washing machine, a carrier chamber; vertical shafts opposite the ends of the carrier chamber; double sheaves on said shafts; upper and lower carrier chains trained between said sheaves; vertical dish holders secured to said carrier chains and consisting of strips of metal suitably bent for receiving the plates and provided with inwardly projecting retaining fingers for holding the plates in the holders; support ing members for said carrier chains and engaging said chains between said sheaves; two sets of forwardly and rearwardly projecting spraying nozzles arranged above said holders; and means for forcing cleansing liquid through said nozzles.

In testimony whereof we aflix our signatures in resence of two witnesses.
